Answer: The shirt originally cost 125 dollars.
Step-by-step explanation: The shirt on sale is 25% off. So first multiply 25 by 5 and you get 125. So 125 is the originall price. Her final cost is 25 dollars. Last step: 125 divided by 5 equals 25 dollars.
That's the cosine x. The cosine of 0 is 1, so that's how you can tell. The sin of 0 is 0, so that's where the sin graph goes through the y axis

7/(b-36)=28/b
28b-1008=7b
21b=1008
b=48
a/72=28/b
a=72x28/48
a=42
Answer:
y
Step-by-step explanation:
8 nickels = 40 cents
y < 8
x < 35
Let's test
1 nickel and 35 pennies. That doesn't work
4 nickel and 20 pennies. That works. Perhaps we be more precise?
5 nickels and 15 pennies. Right on the point. 20 coins.
Hope this helps :)
Have a nice day!
